问题描述
我使用Json数组来显示来自服务器的数据。
I used the Json array to show data from server.
当我将CellIdentifier更改为我在CellIdentifier中使用的@Cell时，pushDetailView正在工作，它将会下一页，但当我再次更改为CustomCell时，只需在第一页显示城市和州的名称，当我点击它时，不会转到下一页。我需要@CustomCell的原因是因为我在第一页需要2个标签视图，当我将其更改为@cell时它只显示一个标签。
when I change the CellIdentifier to @Cell which i used in CellIdentifier the pushDetailView is working and it's going to next page but when I change to CustomCell again just show the name of city and state in first page and when i click on that doesnt go to next page. the reason I need the @CustomCell because I need 2 labels view in first page and when I change it to @cell it just show one label.
谢谢。

推荐答案
如果在推入单元格时没有segue用于自定义单元格，则会调用方法didSelectRow：将调用AtIndexPath。您可以使用该方法自己执行pushViewController或[self performSegueWithIdentifier：@pushDetailViewsender：self];
if you don´t have segue for your customcell when you push in a cell your method didSelectRow:AtIndexPath will be called. You can do yourself a pushViewController from that method or [self performSegueWithIdentifier: @"pushDetailView" sender: self];
